About 13% of Black Friday insurance claims were related to rear-end collisions, 11% from collisions with parked cars and 8% from drivers backing into another vehicle.

Drivers should proceed more slowly than usual and use passengers in the car as extra eyes and ears, said Maria Cashy of the Progressive claims department in a statement.

“Protecting your car can be as easy as parking it a little further back in the parking lot, away from the commotion of the store,” Cashy said. “That extra 100 feet could save your car some serious damage.”

Roughly 147 million people will visit stores this weekend, according to National Retail Federation data. Many will be looking for a place to park.
